Package: Couldn't normalize path in `addResourcePath`


I packaged a shiny app and it's working fine locally. However, when I try to run it in other machines, I got this error

Warning: Error in value[[3L]]: Couldn't normalize path in addResourcePath, with arguments: prefix = 'htmlwidgets-1.4'; directoryPath = 'C:/Users/Gaston/Documents/R/win-library/3.6/htmlwidgets/www'

[No stack trace available]

I read this might be due to the packages version and/or Rstudio. Below is my sessionInfo()

This is related to shiny::addRessourcepath and I had an onLoad.R function where I mentioned addResourcePath

#' Adds the content of www to where/
#' @importFrom shiny addResourcePath
#' @noRd
.onLoad <- function(...) {
  shiny::addResourcePath("where", system.file('www', package = "MyPackage"))

In the ui.R file, I used for example img(src = "where/image.png"))

Grateful for any help.


Would you be able to provide the app code?

Are you sure you did not specify an absolute path somewhere in your code or set a working directory? This could lead to issues when deploying the app elsewhere...

Hope this helps,

Hi @pieterjanvc, thanks for your answer. I edited the question. Hope this provides some more details to the question.

Hello. I was able to overcome the issue by avoiding all packages that import htmlwidgets.
The same issue was reported here but not yet solved.
